Cats Biology

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

Why do women live longer than men? Why do women have menopause? Why are women more likely to get Alzheimer’s? Why do girls score better at every academic subject than boys until puberty, when suddenly their scores plummet? And does the female brain really exist? In Eve, Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as "junk," sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes.

Many people believe that, at its core, biological sex is a fundamental, diverging force in our development. According to this familiar story, differences between the sexes are shaped by past evolutionary pressures - women are more cautious and parenting-focused, men seek status to attract more mates - re-created in each generation by sex hormones and male and female brains. This, in turn, is the basis of supposedly entrenched inequalities in our modern societies.

Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex. Eve is not only a sweeping revision of human history, it's an urgent and necessary corrective for a world that has focused primarily on the male body for far too long. Bohannon's findings will completely change what you think you know about evolution.

The domestic cat—your cat—has, from its evolutionary origins in Africa, been transformed in comparatively little time into one of the most successful and diverse species on the planet. Jonathan Losos, writing as both a scientist and a cat lover, explores how researchers today are unraveling the secrets of the cat, past and present, using all the tools of modern technology, from GPS tracking (you’d be amazed where those backyard cats roam) and genomics (what is your so-called Siamese cat . . . really?) to forensic archaeology.

More than anything else, this is a book about love. In this deeply moving account, you will hear about Rambo, a sheep who informs the staff when another animal is in trouble; and Paulie, a former cockfighting rooster who eats lunch with humans; Dino, an old toothless pony who survived a fire; and many more. Alongside these horses, roosters, pigs, sheep, rabbits, cows, and other animals is a staff of loving humans for whom every animal life, even that of a frog rushed to the vet for emergency surgery, has merit.
